This invention relates to a commercial vehicle suspension assembly that includes an axle, a rack and pinion steering assembly, and a pivot mount assembly for connecting the rack and pinion steering assembly to the axle of the vehicle. The pivot mount assembly controls a pivoting motion of the axle relative to the rack and pinion steering assembly. The pivot mount assembly comprises a clamp portion and a mounting portion. The clamp portion is configured to support the rack of the rack and pinion steering assembly. The mounting portion is configured to attach the rack and pinion steering assembly to the axle.

Commercial vehicle suspension assembly

This invention relates to a yoke assembly () adapted for use in a rack and pinion steering gear assembly () for a vehicle. The yoke assembly () includes a yoke housing () having a bore (). The bore () defines an inner surface (). A bearing () is disposed in the bore (), the bearing () defining an outer surface (). A ring () is also disposed in the bore (). The ring () includes an inner contact surface () and an outer contact surface (). The inner contact surface () engages at least a portion of the inner surface () of the bore () and the outer contact surface () engages at least a portion of the outer surface () of the bearing ().

Rack and pinion gear yoke assembly

A fluid power assist rack and pinion steering system ( ) for a vehicle having steerable wheels comprises a rack ( ) connected with steering linkage of the vehicle for, upon movement of the rack, moving the steering linkage to effect turning of the steerable wheels. A rotatable pinion ( ) is in meshing engagement with the rack ( ). The steering system ( ) also includes a control valve ( ) comprising a valve core ( ) rotatable relative to a valve sleeve ( ). A first part ( ) connects the valve sleeve ( ) for rotation with the pinion ( ). A mechanism ( ) resists relative rotation between the valve core ( ) and the valve sleeve ( ) as vehicle speed increases by placing axial force on the valve sleeve. A second part ( ) on the valve sleeve ( ) resists axial movement of the valve sleeve relative to the valve core ( ).
